Tags: MaxBotix Ultrasonic Sensor, MB1033 HRLV-MaxSonar-EZ3

Features of the MB1033, HRLV-MaxSonar-EZ3, include millimeter resolution, a narrow beam as well as excellent side object rejection, short to long-distance detection, range information from 300mm to 5000mm, a 10Hz read rate, and various output options: pulse-width, analog voltage, and a choice of either RS232 or TTL serial.

The MB1033 from the HRLV‑MaxSonar‑EZ line of sensors is a very small, less than one cubic inch, ultrasonic sensor component module. This sensor comes with mounting holes provided on the circuit board for easy installation in nearly all applications.

In addition, the MB1033 offers virtually noise-free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.
